Title: Improvements in nozzles for delivering liquids
IPC: B05B1/12
Filed: 1939-07-21
Abstract: 532,238. Nozzles. PYRENE CO., Ltd., and HUNTER, J. N. July 21, 1939, No. 21697/38. [Class 69 (iii)] A nozzle for delivering either a jet or spray comprises an inner member 1, and an outer member 3 in the form of a cup to rotate partially around the inner member between two limiting portions, both members being formed with eccentric bores 5, 10 at the same radius from the axis and so shaped that in one limiting position the bore 10 on the outer member wholly uncovers that on the inner member to deliver an unbroken jet, while in the other limiting position the bores are partly in register and present a crescent shaped opening as shown in Fig. 3. The limiting portions are determined by a spring pressed ball 11 entering recesses 9 at the ends of a groove 8.
Patent GB-239363-A (GB)
Title: Improvements in methods of making arsenical salts
IPC: C01G28/02
Filed: 1924-09-15
Abstract: A neutral or slightly basic solution of a solution of an arsenite such as sodium arsenite formed by dissolving arsenic trioxide in caustic soda is electrolyzed with insoluble electrodes of iron or other material to form an arsenate.  When no diaphragm is used hydrogen is given off at the cathode and a small amount of arsenic is reduced, appearing in the solution as small black particles.  By using a two-compartment cell with the arsenite as anolyte, the production of arsenic is prevented, but the electrical efficiency is less.  The arsenate solution is filtered and may be added to a solution of calcium chloride or a suspension of calcium hydroxide to precipitate calcium arsenate. In the latter case, sodium hydroxide is produced, which is filtered off and used in the production of more sodium arsenate. Alternatively, calcium and lead arsenites may be oxidized in a cell containing sodium arsenite as electrolyte. Calcium arsenate and lead arsenate may be used as insecticides.

Title: Improvements in or relating to apparatus for winding flexible sheet material into a roll
IPC: B65H23/02
Filed: 1966-05-17
Abstract: 1,136,454. Feeding webs. W. D. KENNEDY. 8 May, 1967 [17 May, 1966], No. 21794/66. Heading B6B. In apparatus for winding a web of material such as towelling on to a motor-driven mandrel, the transverse position of the web is controlled by the pivotal movement of a rod 13 around which the web passes before reaching the mandrel. As shown, the rod 13 is carried by a bracket 22 pivoted centrally at 14, but the pivot may be adjacent to one end of the rod. Fixed to the bracket 22 near its ends are downwardlyprojecting members 25, 30 with rubber sleeves 31, 32 and movable in slots in a support bench 9 to limit the pivotal movement of the rod 13. Attached to the member 30 is a spring 19 tending to rotate the rod 13 in one direction about the pivot 14, whilst the member 25 is secured to the piston-rod of an air jack 23 which when operative rotates the rod 13 about the pivot 14 in a reverse direction to that caused by the spring 19. The jack 23 is connected by a pipe 34 to a diaphragm-operated valve 26 to which an air supply pipe 36 is connected. The diaphragm is actuated to operate the valve 26 and thus the jack 23 when pressure air is admitted to a nozzle 27 connected by a pipe 28 to the valve. The end of the nozzle is situated opposite to an aperture 15 in and near one end 20 of the rod 13. Air is supplied from a pipe 17 to an internal bore 16 in the rod 13. If the aperture 15 is covered by the edge of the web, no air enters the nozzle, the jack 23 is inoperative, and the spring 19 pivots the bar 13 so that the web is moved laterally away from the nozzle 27. If the aperture 15 now becomes uncovered, the valve 26 is actuated so as to cause the jack 23 to pivot the bar 13 in the reverse direction to move the web laterally towards the nozzle 27. A double acting jack may be employed, in which case the spring 19 is dispensed with.

Filed: 1921-08-23
Abstract: 174,010. Goodrich Co., B. F., (Assignees of Hoffman, H. A.). June 22, 1921, [Convention date]. Balls.-A method of making golf balls comprises curing a vulcanizable cover upon a centre in a heated mould and acid-curing the cover so as rapidly to dry the coating of paint which is subsequently applied to the cover. A preferred means of practising the invention consists in treating a ball having a partially vulcanized cover comprised largely of balata compounded with a vulcanizing substance by immersing it in a dilute solution of sulphur chloride in benzol for a period not exceeding forty-five seconds. The ball is allowed to dry by the evaporation of the benzol and is then varnished and painted. The ball may be immersed in boiling water for about fifteen minutes instead of in the sulphur-chloride solution.

Title: Improvements in associative memory systems
IPC: G11C15/04
Filed: 1961-06-22
Abstract: 983,156. Semipermanent data stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 22, 1961 [July 11, 1960], No. 22585/61. Heading G4A. Data words are stored on a punched card or tape 10 in the form of tag and data digits, words on the card being identified by their tags which are all compared simultaneoulsy with the required tag, a mismatch causing inhibition of a read-out circuit associated with the word having the mismatched tag so that on a subsequent scan of the card only that word having a tag matching the required tag is read out. The card is sensed by energizing electroluminescent strips X 1  to X 10  which extend parallel to the rows of the card (words are stored in card columns), the light passing through holes in the card falling on photo-conductive strips Y 1 , Y 2 , Y 3  . . . located parallel to the card columns. Thus the impedance of a circuit including a Y strip indicates the presence of absence of a hole at the intersection of the X and Y strip. Three five-digit words are shown as punched on the card 10, binary 0 or 1 being indicated by the presence of a hole in the upper or lower position of the two allotted to each digit of the word. The first three digits of a word form its tag. Assume that a word with tag 011 is to be found and read out. The tag is set up in complement form by applying an A.C. signal to strips X2, X 3  and X 5 . Photo-conductive strips Y 1  and Y 3  will have low impedance due to holes X 2 Y 1  and X 2 Y 3 , X 3 Y 3  and X 5 Y 3  in card 10, and only strip Y 2  will present a high impedance to input C 4 . In Fig. 2 the diodes D 1  to D 18  are normally forward biased by the potentials at points P 1  to P 9  due to the reset condition of latches 19 to 21. Anode voltage comes from lines S 1  to S 6 . The low impedance of strips Y 1  and Y 3  sends P 1  and P 3 , and it is assumed P 4  to P 9 , positive, blocking diodes D 1 , D 2  and D 5  to D 18  and sending all the sense lines except S 2  and S 4  positive. At T 1  gates 22 to 24, and 31 to 33 are opened, the conditions of the sense lines being such that latches 25, 27 and 34 are set (circuits 28 to 30 are inverters). At T 2  gates 28 to 30 are opened to set latches 19 and 21 and provide positive control voltages on lines C 1  and C 3 . The data digits are then interrogated by successively pulsing with A.C. the strips X 1  to X 10 . Since lines C 1  and C 3  are positive only those diodes D 3 , D 4 , D 9 , D 10 , and D 15  D 16  connected to line C 2  can change their state in response to changing potentials on the read-out lines from the Y strips. Of these, only diode D 3  which is connected to point P 2  is connected to line S 4  which is the only sense line feeding an open output gate 37. Thus the outputs from circuit 43 represent the digits punched in the column of card 10 associated with strip Y 2 .
